Electron microprobe analyses of feldspars from the Hawkeye and Lyon Mountain Granite Gneisses in the Adirondacks of New York.

Iron oxide-apatite (IOA) deposits of the Adirondack Mountains of New York locally contain elevated REE concentrations (e.g. Taylor and others, 2019). Critical to evaluating resource potential is understanding the genesis of the IOA deposits that host the REE-rich minerals. As part of this effort, the U.S. Geological Survey (USGS) is conducting bedrock geologic mapping, geochro

Data release for structure-from-motion DEMs derived from historical aerial photographs and their use in geomorphological mapping

This data release publishes datasets within and surrounding the Piney Branch watershed located in the Washington, D.C. metropolitan suburb of Vienna, Virginia. This dataset was utilized in studies that investigated the accuracy and application of geospatial modeling techniques, structure-from-motion (SfM) photogrammetric methods, and digital elevation model (DEM) differencing to a

Physico-chemical characteristics and sediment and nutrient fluxes of floodplains, streambanks, and streambeds in the Chesapeake Bay and Delaware River watersheds

Dataset includes site averages of measurements of floodplain and streambank sediment physico-chemistry and long-term (dendrogeomorphic) vertical and lateral geomorphic change, and reach scale floodplain width, streambank height, channel width, and streambed particle size. This information was used to calculate fluxes of sediment, fine sediment, sediment-C, sediment-N, and sed

Digital Data for the Geology of the Mineral and Lake Anna West quadrangles, Virginia

This Data Release contains 1:24,000-scale geospatially-enabled geological data to accompany the Geology of the Mineral and Lake Anna West quadrangles, Virginia. The map product is a cooperator series publication and, as such, does not have a specific abstract. Geologic mapping for this map product was completed between 2014 and 2017, with most of the field work occurring between Janua

Soil characteristics and microbial taxonomy in selected urban stormwater best management practices (BMPs) in Clarksburg, MD, 2015

The data were gathered as a preliminary assessment of soil microbiology and conditions in selected urban stormwater best management practices (BMPs) in Clarksburg, MD. Four bioretention facilities (BF), four dry ponds (DP), and four surface sand filters (SSF) were selected. Three samples were taken from each BMP (a single sample from one dry swale (DS) was also collect

Revised PRISM3 Pliocene Sea Surface Temperature Estimates

Model experiments that attempt to simulate climates of the past serve to identify both similarities and differences between two climate states and, when compared with simulations run by other models and with geological data, to identify model-specific biases. Uncertainties associated with both the data and the models must be considered in such an exercise. The most recent period of sustained...

Inventory of Artisanal and Small-Scale Mining (ASM) in Shaida: Points (2017 to 2019)

Afghanistan is endowed with a broad range of mineral resources. Currently, the majority of mining throughout the country is comprised of informal and undocumented artisanal and small-scale mining (ASM) operations. The exact scope of excavation operations depends largely on the mineral commodity produced. In the case of gemstones, such as emeralds and rubies, small teams of miners use ma
